How Do I Prevent Furnace Condensate Overflow in Cary?

What we found and did
A Cary homeowner in the 27513 area had the existing condensate drain system removed and converted to a condensate pump system. Because of space constraints next to the furnace, the new condensate pump was installed in its own dedicated auxiliary drain pan. The team added an SS2 inline safe-T-switch on the primary drain line for secondary overflow protection and wired it, along with the pump safety overflow switch, into the low-voltage control circuit (R/Y) so the equipment shuts down automatically in the event of a backup or pump failure. They also placed and secured up to 20 feet of discharge tubing to route condensate to the designated drain termination point.
Result
The pump reservoir was filled to confirm automatic float activation, the tubing run was verified leak-free, the safety switch shutoff was tested, and the system was fully operational.
